I have two users that have different roles but the same profile.
I cleaned up some page layouts for our lead and contact objects and am testing them with a particular set of users. No issues with the people I know are testing.
However, someone from another department said they said their page layouts changed too. I compared her profile to someone else in her department, and they matched. I verified one has the updated layout, and the other doesn't.
I went to check Page Layout Assignments for both objects and confirmed their profiles should have the default layout.
I verified their profiles were the same in Setup --> Users
I am not a certified Salesforce admin by any means. I can move my way around objects and some basic formulas. We're a small company (about 30 people in total) and don't have a Salesforce admin.
How can this have happened?
Where should I look to find more information?
How can I resolve this?
I'm in Salesforce Enterprise Edition (Classic)
